Hey bartc.. I also did a John Risch SQ&D Digital ISO Tranny, but I used the original RS trannies. Since I made the move to separates I started using the Topaz

It is big, unsightly and does hum slightly.

I have a Signal DU-.5 that I could use or I could go the SQ&D route with a pair of larger trannies. I just wonder if after i get a decent case, power cord, and a couple of nice receptacles, would the Tripp-Lite be a viable, more cost effective option?

Thanks for your valued opinion.

BTW, I must agree, used within it's limits, John's SQ&D ISO works great (Thanks John!)

Sadly, my Iso Trannies also vibrate. I'm afraid that all transformers do so some extent, so don't let that alone dissuade you. Just compensate for it.

Here's the rub: Isobar and other Tripplite products do have some of the kinds of components that Jon Risch does not recommend having in your AC system. At least I think they do: switches, MOVs, etc. So swapping the outlets and the PC and the plug, still gets you the same metal case (for good sheilding or detrimental effects, I don't know which!), and the same no-no components. That's why I don't use it with my amp/receiver; only with my sub and an RF amp I use for FM reception, as those seem to benefit from the shielding and filtering rather than losing something. Amps lose something, as do CDPs IME with these products.

If you're going to the trouble to construct something from all good parts, just go the whole hog and do another Iso Tranny. Do a good job of vibe control, use some ALan Maher Infinity units over the trannies. The R-C array is sort of built into the design already. Do consult Jon on the right values if you change from his formula.

And I simply don't know whether you're better off with a metal box (shielding) or a non-metal one. If you go for metal, please do take Al Sekela's advice and avoid ferrous metals altogether.

  Someone was willing to give up their Tripp-Lite. That's the only reason I had given it any thought.
  
  Putting together a larger SQ&D Digital ISO is the direction I'll head in. I'm going to keep an eye out for a pair of suitable transformers on EBay, then I'll look for an aluminum case as budget allows
  
  Thanks for sharing your thoughts. I really appreciate it!

    Hi,
    
    Look at a Blue Circle Audio PLC (Power Line Conditioner) Thingee - I have one and it works great on CD and DVD front end gear. Not pretty, but does a very good job at a decent price, if you don't want the DIY approach.

      Thanks! It looks like a great product and the price is right!
      
      The only problem I see is the one Duster mentions, concerning the PS Audio Soloist I already have installed. That is not being able to experiment with different brands/makes of outlets.
      
      Thanks Again
